ABSTRACT:
A method for applying a mechanical massage while the back of a user is against the back rest of a chair or lying on a bed uses a massage mechanism unit having a pair of spaced parallel arm members and a massaging wheel rotatably supported on one end of each of the arm members. The massaging wheels are positioned on the back of the user on opposite sides of the spinal column. The massaging wheels are then simultaneously moved and turned in the same direction from left to right and right to left while moving back and forth along sinusoidal paths on two sides of the spinal column. The pressure exerted by one of the massaging wheels on the back is reduced by moving the massaging wheel away from the back as the massaging wheel moves closer to the spinal column. The pressure exerted by the other massaging wheel is increased by moving the massaging wheel toward the back as the massaging wheel moves away from the spinal column. The massaging wheels thus alternatingly move toward and away from the spinal column. The massaging wheels apply the same amount of pressure on the user's back and are at the same height relative to the spinal column when equally spaced from the spinal column.
